300gramwheat flour(preferably with 12% protein content)
150gramItalian flour(or fine bread flour)
Equipment
Baking sheet + rack
Baking paper
INSTRUCTIONS (how to make this recipe):
Pour the water into a large bowl and mix in the salt. Then add the sourdough starter, followed by the flour.
Mix until everything is well combined and there is no loose flour left in the bowl. Cover with cling film and leave to rest for 30 minutes. Then perform four sets of stretch and folds, with half an hour between each set.
Next, place the dough in a large, rectangular container, preferably transparent. This will allow you to see how far the dough has risen. Mark a line on the container and, once the dough has risen by about 75% after 4–6 hours in a warm place, put the container on top of the refrigerator and leave the dough to rise for a further 12–24 hours.
Once risen, sprinkle some flour over the dough in the container and plenty of flour on the countertop. Turn the dough out onto the countertop. Carefully stretch it out into a rectangular sheet. Using a dough scraper or large knife, cut the dough in half vertically so that you have two long rectangles.
You can then cut each piece into four pieces and shape them into eight small ciabattas. Alternatively, you can choose to make two long ciabattas, in which case you can skip this step.
Spread the dough on a rack covered with baking paper (not a baking tray). Leave to rise for another hour — because the dough has already had a long rise, it will not grow much larger during this time.
Preheat the oven to 230 degrees Celsius / 445 Fahrenheit with top and bottom heat. Place a baking sheet under the rack (place the rack in the middle of the oven). Slide the ciabattas onto the rack in the oven, then immediately add some water to the baking sheet underneath to create steam. Close the door quickly.
Bake the rolls for about 15 minutes until golden brown. Leave to cool for a moment and enjoy!
